Ontology for Semantic Data Description in Scientific Domain
Journal Title: RECENT - Year 2012, Vol 13, Issue 34
Abstract
The scientific data obtained from different experiments are heterogeneous and stored in different file formats. Discovering, integrating and distributing of such data are challenges nowadays. OWL ontology for semantic data description is proposed in this paper. The ontology structure including classes and property hierarchy and relationship of the general ontology is explained. An RDF instance of the input XML file on the basis of the ontology is obtained. This should allow efficient description, storing, discovering and interpreting of the scientific data through the semantic web. A software framework for transforming raw data obtained from various scientific experiments into RDF instances on the basis of XML data description and the proposed ontology is developed. The framework is implemented as web service and consists of several key elements: XML scientific data description; ontology describing in detail the significance of semantics and XML data; the correspondence between the XML schema and OWL ontology is determined in accordance а mapping document. A number of experiments using specific scientific dataset in the cases of physical field data as radiation and spectral measurements obtained from experimental instruments are conducted to illustrate the usage of the proposed ontology and the software framework.
